Answer:
The event that led to the others:
C. Sylvia was forced to attend an inferior school.
A. The Mendez family sued their school district.
D. Four districts in California ended segregation.
B. Sylvia started attending 17th Street Elementary.
Step-by-step explanation:
The above events formed the beginning of the landmark judgement that ended the segregation of American schools, starting from 1945. Five Mexican Americans: Sylvia, Gonzalo Jr., and Geronimo Méndez had dark skin, hair, and eyes, while their nieces: Alice and Virginia Vidaurri had white skin, hair, and eyes. As a result, Sylvia and siblings were not admitted into the 17th Street Elementary while Alice and Virginia were admitted. As a result, the Mendez family sued the Westminster School District. In 1946, the federal court ruled that establishing separate but equal schools for Mexican American children in Orange County, California was unconstitutional.
